SPECIFICATION forming part of Letters Patent No. 743,697, dated November 10, 1903.

Application filed October 20, 1902. Sra-l No. 128,080. v(No model.)

zen of the United States, residing at Los Angoles, in the county of Los Angeles and State of California, have invented a new anduseful.

, Atomizer, of which the following is a specification.

This invention is designed for breaking up and atomizing liquids under pressure of an expansive iiuid for spraying or distributing the liquid.

A special object of the invention is to provide means whereby thick hydrocarbons may be reduced to vapor and supplied in perfectly-regulated quantities to the fire-box of a furnace, so that the fire may be constantly maintained at any determined volume and force.

A further object of my invention is to provide an atomizer of simple, cheap, and durable construction, which shall be positive and eiiicient in operation and in which wear of the several parts is reduced to a minimum.

A further object is to provide simple and effective means Vfor preventing any clogging, owing to the usual presence of sandor grit, in heavy thick hydrocarbon oils.

To these ends my invention consists in an atomizer having a vaporizing-chamber, revoluble means therein for breaking heavy oil, an

inlet adapted to deliver steam or otherexpansive medium under pressure againstsaid revof luble means to operate the same, an inlet axial with respect to the revoluble means, adapted to deliver liquid at the side of said revoluble breaking means, means whereby said liquidinlet is regulated, and revoluble means whereby clogging of said liquid-inlet is prohibited.

More specifically, my invention consists in an atomizer having a body comprising a vaporizing-chamber, a hollow shaft entering said cha mber axially, a revoluble breaker and mixer loosely mounted on said shaft, the face of said mixer provided with a series'of flights radiating from the center, a tangential expansive-medium inlet adapted to direct its stream against the periphery of said mixer, an outlet, and means whereby the duct through said shaft may be entirely or pariially closed to regulate the entrance of liquid to said chamber.

The invention consists, further, in the devices, constructions, and combinations of particularly pointed out in the claims.

The radiating 'flights 17 form aser-ies `of open ways or channels, and the flights serve to cause a greater agitation and better commingling of the oil and steam.

The invention will be more readily understood by reference tothe accompanying drawings, forming part of this specification, and in which- Figure I is a vertical sectional view on line I I of Fig. II. Fig. II is a top plan view, partly'in section. Fig. III is a vertical sectional view on the line III III of Fig. IV and shows my atomizer as designed more especially for use with an expansive medium under pressure and liquid supplied thereto without pressure. Fig. IV is a top plan view, partly in section, of the atomizer shown in Fig. III.

-As shown in the drawings, the breaking and mixing chamber is formed of the section '2, provided with a cylindrical chamber 3, and' a side wall'or cover-section 4, adapted .to be secured together in the ordinary or anysuitable manner. Through the center of the wall 2.1 provide a duct 5, which runs through the projection 6, extending inwardly from the wall 2 andforming a hollow shaft 0r hub for the rotary breaker andinixer 7,loosely mount- Y ed thereon,the shaft extendingnearly through 'the breaker and the duct therein communi- :eating into the `chamber through the port 8. An inlet through the wall 2 registers with the duct of the shaft 6. The end of the shaft 6 is beveled, as shown, and the wall of the bearing in the breaker 7 is provided with an inclined wall 9, near to which this beveled end operates. It will be noted that a slight clearance is thus provided, for theY purpose hereinafter mentioned, between the end of the shaft-.and the opening or port 8.. The periphery of the breaker' and mixer 7 is provided with a series of teeth, as shown, and the side opposite the shaft or huby 6 is provided with a series of iights 17, radiating from the port 8.

The wall is provided with an inlet l0 for steam or other expansive material. This in-K,

parts, all as hereinafter described, and more IOO let enters the chamber at a tangent and is adapted to direct the jet of steam against the toothed periphery of the breaker and`mixer 7. Opposite the inlet 10 is a tangential outlet 18, which, as shown, isof greater area than the area of the inlet-ports 8 and 10.

The cover-section 4 is provided with a threaded bearing 11, into which the liquidinlet regulator l2 is adapted to be screwed. This regulator is in turn connected with an arm 13 by a nut 14. A set-screw 15 passes through this arm and is adapted to hold the regulator in the desired position. A packinggland 16 is provided, as shown, about the regulator 12.

The operation is as follows: A-jet of steam under pressure is introduced through the'inlet 10 and strikes against the toothed periphery thereof, causing the breaker and mixer to rotate rapidly. A stream of oil passing through the inlet and hollow shaft or hub G is discharged against the wall 2 of the chamber, and the flights 17 accentuate the breaking of the oil and its thorough mixing with the steam therein. The resultant vapor passes out from the chamber through the outlet 18. All sand, sediment, or heavy material whichmight cause the clogging of the port Sis ground up between the end'of the hub 6 and the inclined wall or seat and the Wallsurrounding the port 8. By releasing the set-screw 15 and throwing the arm 13 the regulator 12 is turned toward or awayfrom the port 8, regulating the discharge of oil therefrom. By this means 1 provide .a device which thoroughly breaks up heavy thick oil and intermingles it with steam, forming a quick and readily burning vapor. I provide a removable and renewable seat yfor the rotary breaker. This consists of' the washer 19, preferably of brass, inserted on the hub 6 between the wall and the side of breaker shown.

In Figs. III and IV, I have shown a modification of the atomizer of Figs. I and II. As shown in Figs. III and IV, the flights 17 are covered by a plate or disk 20, which is secured on the flights by screws 21 or by any other suitable means. This plate or disk, if desired, may be formed integral with the flights 17, the same being cored ont in castings, and where- I hereinafter refer to such plate 20 I include either constructing the same as a plate fixed on said flights or as integral with the breaker. It is thus seen that in this form channels or ducts are formed between the side of the rotary breaker and the plate or disk 2O by the flights 17. As shown, thc inclined wall 9of the bearing in the breaker and the inclined portion of the hollow hub or shaft are omitted and the hub or shaft adapted to extend out flush with the side or face of the breaker, the plate 20 being construction shown in Figs. III and IV, I am enabled to use my atomizer in connection with a liquid-supply without providing pressure for forcing the liquid into the atomizer. The expansive-medium stream under pressure striking the teeth on the periphery of the breaker, rotating the same, causes centrifugal action, by which the induction of the oil to the breaking-chamber is accomplished.

It is obvious that many equivalents for constructions and parts shown will readily suggest themselves to one skilled in the art, and I therefore do not con fine myself to the exact construction shown or described, but may use many mechanical equivalents therefor.
